	<span lang=\"EN-US\" style=\"font-family:Verdana;\">Most of the researches on profit and cost evaluation of
redundant system focus on the effect of failure and repair on revenue
generated. However, as these systems continue to work, their strength gradually
deteriorates. Where such dete</span><span lang=\"EN-US\" style=\"font-family:Verdana;\">rioration occurs, minor and major maintenance </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">is</span><span lang=\"EN-US\" style=\"font-family:Verdana;\"> employed to remedy the deterioration. Little or no attention is paid on the
effect of deterioration on</span><span lang=\"EN-US\" style=\"font-family:Verdana;\"> the</span><span lang=\"EN-US\" style=\"font-family:Verdana;\"> impact of deterioration and their
maintenance on the revenue generated. In this paper, we study the profit
generated of two-stage deteriorating linear consecutive 2-out-of-3 system.
Failure, repair and dete</span><span lang=\"EN-US\" style=\"font-family:Verdana;\">rioration time are assumed exponential. The
explicit expressions of availability, busy period of a repairman and profit
function are derived using KolmogorovĄ¯s forward equations method. Various cases
are analyzed graphically to investi</span><span lang=\"EN-US\" style=\"font-family:Verdana;\">gate the effect of deterioration parameters
such as slow deterioration, fast deterioration, and their maintenance such as
minor and major minimal maintenance on profit generated.</span>
